Title: Arc starting control device of welding robot
Inventor: SAITO YASUO
IPC: B23K9/12

Abstract: PURPOSE:To generate an arc easily with destroying automatically the insulation on the surface of a base metal by starting the normal feeding of a wire in the number of set times with detecting an arc current and by providing the control part to perform the continuation, abnormality decision, etc. in welding. CONSTITUTION:The first control part moves a welding torch 5 along a base metal 8 and makes a wire 2 cut into the insulation of the base metal 8 simultaneously. The detector 11 inserted into the mid position of the wire 2 detects the arc current and transmits the signal to a robot control part 6 via the control part of a welder 3. The signal of non detection is transmitted to the control part 6 as well. The second control part re-starts the normal feeding of the wire 2 and the movement of the torch 5 after reverse feeding of the wire 2. The third control part moves the torch 5 and wire 2 with confirming the detection of the arc current and continues the weld work. The fourth control part decides the abnormality with confirming the time of re-starting in the number of set times and the time of the arc current being not detected.

Title: Magnetic recording medium
Inventor: IKUYAMA SEIICHI
IPC: C08L79/08
Filed: 1992-09-04
Abstract: PURPOSE:To eliminate sticking of tape in the running system by forming a non-magnetic base material with a material mainly consisting of polybenzoxazole having the predetermined structural expression. CONSTITUTION:A magnetic recording medium is obtained by forming a magnetic layer 2 on a non-magnetic base material 1. This non-magnetic base material 1 is formed by a material which is mainly consisting of polybenzoxazole represented by the structural formula. In the formula, n is ranged from 20 to 200. The non-magnetic base material 1 contains polybenzoxazole of 70wt.% or more and total thickness is set to 0.8mum or less. Moreover, the non-magnetic base material 1 may include fine powder of colloidal silica as a filler. Since polybenzoxazole which is the main structural material of the non-magnetic base material 1 has a higher Young's modulus as explained above, any sticking of tape is never generated, and the edge portion is nevery damaged, the tape is favorably used as a thin and long length magnetic recording medium.

Title: Repeater
Inventor: SOGA TADASHI
IPC: H04B10/079
Filed: 1995-10-11
Abstract: PROBLEM TO BE SOLVED: To obtain the repeater through which a subordinate device detects an alarm display signal immediately by operating a signal transmission section with an asynchronizing signal whose phase is in matching with a synchronizing clock signal. SOLUTION: When a line is interrupted, a phase comparator 31 compares a phase of a synchronizing clock from a frame synchronization circuit 13 with a phase of an asynchronizing clock from an internal oscillator 19. Then the phase of the asynchronizing clock is delayed with a delay circuit (DLY) 32 by a phase difference detected by the phase comparator 31. Then a selector (SEL) 18 selects an internal oscillator 18 to activate a signal transmission section 14 with its asynchronizing clock whose phase is in matching with the synchronizing clock. Since the phase of the clock at an input terminal of the SEL 18 is matched, a phase of output data from a signal transmission section 14 is not rapidly changed and no out of frame synchronism is detected by a repeater and a multiplex terminator at a subordinate stage and an alarm display signal is immediately detected.

Title: Still video recording method
Inventor: NITTA HITOSHI
IPC: G11B27/10
Filed: 1989-10-09
Abstract: PURPOSE:To perform recording from a specified track which keeps continuity by erasing a still image on a recording track where the still image is recorded first of all when the still pictures are recorded on all the recording tracks of a recording medium. CONSTITUTION:When a floppy disk 4 is loaded, the recording track whose number of subscript is the smallest is retrieved out of the recording tracks 6n where the still image is not recorded, and a magnetic head 12 is moved to be opposed to the recording track 6. When the still image is recorded on all the recording track 6 of the disk 4, the still image of the recording track 6 next to the recording track where the still image is recorded last, that means, the recording track 6 where the still image is recorded first of all is directly erased. Therefore, even when the disk 4 is unloaded, the still image is recorded in a state where the continuity is kept by reloading the disk 4.

Title: Fm signal demodulator
Inventor: YAMAGUCHI KOICHI
IPC: H03D3/00
Filed: 1987-10-21
Abstract: PURPOSE:To reduce impulsive noise caused when C/N of a signal is lower then the threshold value by using plural FM demodulation circuits and noise reduction circuits whose high frequency transmission characteristic is made different so as to reduce only the non-correlation noise component relatively. CONSTITUTION:A circuit varying slightly a high frequency transmission characteristic is arranged to a pre-stage of an amplitude limiter circuit. Thus, demodulation signals at demodulation outputs 10, 11 have nearly similar waveform but the production time with respect to pulse noise generated is not correlative. Since the pulse occurrence frequency is small when the C/N reaches the vicinity of the threshold point, the probability of both output pulses to be overlapped is small and the state has nearly no correlation. Thus, only noise component is reduced by a noise reduction circuit 12 by utilizing that the two signals at the demodulation outputs 10, 11 are the same and the pulse noise has no correlation. Then the pulse noise caused when the signal C/N is lower than the threshold value is reduced.
